Jacked Factory is a supplement company with a small but well known range of products, they are perhaps best-known for their pre-workout “Altius” which has been getting rave reviews for a while now. Androsurge is an anti-estrogen supplement that frequently comes out as the best on the market in supplement top ten lists.
A single bottle comes with 60 capsules, and the company claims that they can block estrogen, boost testosterone, build lean muscle, burn fat, and boost energy. Interestingly they don’t mention lowering stress which is odd as one of their ingredients “Eurycoma Longifolia root extract” is well known to do so.
The claims made by this company all stack up, but it’s a little more complicated than that. They claim that the capsules increase muscle and burn fat, but this is because the product boosts testosterone, which is the result of the ingredients being effective estrogen blockers. In other words, the benefits have all been written separately but are actually all linked. There’s nothing really wrong with this, but it’s definitely worth mentioning.
There aren’t many ingredients present inside Androsurge, but in truth this is usually a good sign for a supplement company. Too many companies try to throw as many ingredients into a capsule as they can in attempt to impress the purchaser. But having effective doses of just a few ingredients is usually as effective (if not more) than having lots and lots.
Other than Vitamin D and Zinc, the main ingredients are: Grape Seed Extract, DIM, Rhodiola Root Extract, Eurycoma Longifolia Root Extract, and BioPerine (which is used to increase absorption). We’ll take a more detailed look at the first four main ingredients now.
This ingredient contains two estrogen blocking ingredients, they work by inhibiting the enzyme aromatase. Blocking this can prevent aromatase from turning excess testosterone into estrogen. Androsurge contains 150mg of Grape Seed Extract per serving.
Diindolylmethane is another aromatase inhibiting ingredient that is found in cruciferous vegetables (kale, Brussels sprouts, broccoli, and cabbage). It works in the same way that Grape Seed Extract works, and is effective at altering estrogen when dosed at 100mg. Androsurge contains 150mg per serving, so it definitely provides an effective dosage.
Used to lower stress and fatigue, Rhodiola Root Extract is intended as a testosterone protector. Reducing stress and fatigue can lower cortisol (the stress hormone), which reduces testosterone. So by lowering cortisol you are indirectly boosting testosterone, you will also increase your energy (which is one of the claims). Rhodiola Root is considered effective at any dose above 50mg. Androdurge contains 125mg which is lower than some supplements (which contain around 300mg) but still an effective dose.
This ingredient works in a similar way to Rhodiola Root Extract, however it does have a evidence-backed effect on men with low testosterone, one study found that supplementing with Eurycoma Longifolia led to a 46% increase in testosterone in men with severely low testosterone levels . It can also lower anxiety and stress, leading to a decrease in Cortisol.
Androsurge is an excellent supplement that can lower estrogen, prevent the conversion of excess testosterone to estrogen (by inhibiting aromatase) and by preventing testosterone loss due to stress. It won’t help you build muscle and burn fat, not directly at any rate. But it can help you train harder, and if combined with lots of exercise and a healthy diet it should indirectly help you.
The transparency that Jacked Factory has given their product is a nice touch, and they definitely haven’t under-dosed their ingredients (though perhaps Rhodiola root extract could be a little higher), which is a really good sign. Definitely worth a go. You can order ANDROSURGE Estrogen Blocker on Amazon or on JackedFactory.com.
